Jean-Gabriel Pageau got his first NHL hat trick to lead the Ottawa Senators in a fight-filled 6-1 victory over the Montreal Canadiens.

Ottawa and Vancouver combined for 236 penalty minutes and nine players were given a game misconduct in their ill-tempered playoff. The Senators have a 2-1 lead in the best-of-seven series and game four is Tuesday night in Ottawa. The third period started out with the Senators leading 2-1, but after Pageau's second goal of the night and a Kyle Turris goal at 7:00, emotions overflowed and a line brawl broke out at center ice. On the ensuing faceoff, four different fights broke out.

The Senators ended up with the man advantage and Jakob Silfverberg scored on the power play as he beat Habs goalie Carey Price up high to make it 5-1 only 8 seconds after Turris' goal.

The Pittsburgh Penguins shook off an early deficit and a late rally to beat the New York Islanders 5-4 on Sunday, to take a 2-1 lead in their best-of-seven first-round playoff series. Chris Kunitz scored his second power-play goal of the game 8:34 into overtime off a pass from Sidney Crosby for the Eastern Conference's top-seeded Penguins.

Pittsburgh trailed 2-0 just 5:41 into the game, but rallied to lead 3-2 before the first period was over. The comeback started with power-play goals just 19 seconds apart by Jarome Iginla and Kunitz. The Penguins seemed in control in the third period, but New York erased a 4-2 deficit on goals by Kyle Okposo and John Tavares. Pittsburgh will try to take a commanding 3-1 series lead Tuesday night on Long Island.

At St Paul, Jason Zucker scored at 2:15 of overtime to give the Minnesota Wild a 3-2 victory over the Chicago Blackhawks in the Western Conference quarterfinal series. The Blackhawks lead the series 2-1.

Minnesota's Zach Parise scored early in the third period, but Duncan Keith got one back for the Blackhawks with 2:46 left in regulation to force the second overtime in three games. Game four is at Minnesota on Tuesday. Keith's snap shot glanced off Wild defenseman Marco Scandella and past goalie Josh Harding to make the score 2-2.

The San Jose Sharks won their third straight game to open the playoffs, beating the Vancouver Canucks 5-2

At San Jose, Joe Pavelski and Logan Couture each scored twice to spoil Cory Schneider's return to the nets for Vancouver. Pavelski scored the first two goals and Couture and Patrick Marleau added scores 9 seconds apart to break the game open early in the third period and give the Sharks a 3-0 series lead. San Jose will attempt to complete the first series sweep in franchise history at home on Tuesday. Alex Burrows and Dan Hamhuis scored for the Canucks.
